(Phys.org)—New research by Stanford aeronautics and astronautics Assistant Professor Sigrid Close suggests she's on track to solve a mystery that has long bedeviled space exploration: Why do satellites ...

Particles from the upper atmosphere trapped in a deep pile of Antarctic snow hold clear chemical traces of global meteorological events, a team from the University of California, San Diego and a colleague from France have ...

An ultraviolet spectrograph designed by Southwest Research Institute (SwRI) has been selected for flight on the European Space Agency's Jupiter Icy Moon Explorer (JUICE). NASA is funding development of the instrument, which ...

(Phys.org)—Every year, sensors designed to detect nuclear explosions see harmless bursts in Earth's upper atmosphere from the breakup of an asteroid a few yards across. Tiny asteroids are much more numerous ...

(Phys.org)—Measurements obtained with ESA's Venus Express spacecraft have shed new light on the interaction between the solar wind and the second planet from the Sun. During a rare period of very low density ...

In what is believed to be the first study of its kind, researchers used genomic techniques to document the presence of significant numbers of living microorganisms – principally bacteria – in the middle ...

(Phys.org)—Researchers have detected the presence of a pollutant-destroying compound iodine monoxide in surprisingly high levels high above the tropical ocean, according to a new study led by the University ...

The Atmospheric Infrared Sounder instrument that flies on NASA's Aqua satellite provides valuable data to tropical cyclone forecasters, and revealed sinking air, a small area of powerful thunderstorms, and ...

Microorganisms—99 percent more kinds than had been reported in findings published just four months ago – are leaping the biggest gap on the planet. Hitching rides in the upper troposphere, they're making ...

(Phys.org)—When you look up at the stars at night, the space between stars looks empty. But, yes there is something there. It's called the interstellar medium. An experiment from the University of Colorado ...

Tiny sensors—made of a potentially trailblazing material just one atom thick and heralded as the "next best thing" since the invention of silicon—are now being developed to detect trace elements in Earth's ...
